sophos endpoint updating failed

yeowkm

I have a few clients on the non domain segment (DMZ) on my network that are not able to update since I upgrade to a new sophos EC server.

the DMZ clients always shows a updating failed error message.

I have tried reprotecting them from the new server.

    Hello yeowkm,

    alc.log shows Windows error 53 which usually  signifies that the NetBIOS name (GVPTSOPHOS) could not be resolved. Reprotect has likely failed as well. A DMZ is normally walled off which makes NetBIOS name resolution unavailable - guess it worked before because of a specific configuration which has to be adjusted for the new server.

    Hello yeowkm,.

    something must have been done that it worked with the old server - the same something should be done for the new one. The nature of this something depends on your network. It might be more than just name resolution - try to browse to the CID using the server's IP (\\nnn.nnn.nnn.nnn\SophosUpdate\CIDs\) or FQDN (\\server.acme.com\SophosUpdate\CIDs\) instead of the name. If neither works then likely the firewall is also blocking the connection.
